W. H. BURRIDGE, OF CLEVELAND, OHIO.

IMPROVEMENT IN CAR-SASH FASTENINGS.

Specification forming part of Letters Patent No. 45,223, dated November29, 1864.

To all whom it may concern.-

Be it known that I, W. H. BURRIDGE, of Cleveland, in the county ofCuyahoga and State ot' Ohio, have invented certa-in new and usefulImprovements in Railroad-Car Window- Fastenings; and I do hereby declarethat the following is a full and complete description of theconstruction and operation of the same, reference being had to theaccompanying drawings, making a part of this specification, in which-Figure l is a perspective view of the fastening and the part ofthewindow-frame with which it is connected. Figs. 2, 3, and et are detachedsections that will be referred to in the description.

Like letters of reference indicate like parts in the several views.

My improvement relates to a railroad-car window-fastening, soconstructed and arranged that all the parts will come together in placein the most desirable manner, without any trimming or dressing, being anew and useful article of manufacture.

In Figs. 1, 2, and 3, A is a section of the window-trame to which thebolt is attached, as represented in Fig. l. The fastening is formedprincipally of three pieces-the back plate, B, cap C, and bolt D. Theback of the plate B, that comes next the frame, has points or pins b(shown in Fig. 4) at each corner, cast with the plate, that, when forcedinto the frame, producing indentations d, as seen in Fig. 2, hold theplate on the frame in any position and prevent it from moving out ofplace, being held securely by one screw, F, Fig. l, in

the center. On the other side ofthe plate are pointed projections f, atthe middle of each side, to retain the cap C in place on the plaie.

ln the cap are arranged the boltD and spring C', as represented in Fig.3, and at the middle of the sides of the cap are notches c,corresponding with the projectionsfon the plate; and these notches,iitting on the projections f, together with the screw in the center,render the cap immovable on the plate. The screw F, extending throughthe cap and plate into the windowframe, secures the different parts ofthe fastening iirmly together and to the frame.

The faces of the plate and cap form a true square, and as all sides ofeach are equal and alike in form, the plate can be placed any side up ontheframe, and the cap can be putin any position on the plate, all theparts litting together for the desired purpose, as described, theprojections and notch es being cast so as to tit each other accurately,indiscriminately, without any tiling or trimming, which is necessary inordinary window-fastenings.

From the simple construction and arrangement of this fastening, and thereadiness with which it is put together in any position, requiring but asingle screw, greatly facilitates the attachment of bolts to windows andlessens the expense.

That I claim as my improvement, and desire to secure by Letters Patent,is-

The special construction and arrangement of the plate B with points band projections j', in combination with the cap C, notches c, and boltD, as a new and useful article of manufacture. f
